Correct way to quiet squeeky bushings?

[Luxus Panzer]

My rear suspension bushings have an annoying squeak.

The car is lowered so I know the bushings are under extra stress, but they are only 2.5 years old. Yes the bushings were tightened correctly while the weight was on the suspension ;)

Is there any "lube" I can put on my bushings that will not destroy them, or attract a bunch of dirt/grime?

Subbed. I was actually investigating this briefly last night before exhaustion overtook me

Silicon grease comes to mind, use that a lot in marine applications.

ok, any others?

Application method?

Rubber bushings should not be sliding and should not need lube. Are you sure it's the arms?

The sway bar could slide, but that's it.

no slide...just squeak.

A correctly functioning rubber suspension bushing should only be flexing. Flexing bushings don't squeak.

To me that leaves two possibilities.

1: Your bushing is failing and the surfaces are sliding ( causing the squeak).
2: It's something else that making the noise.

Dampers (shocks) can make odd noises. If it is a bushing, you should see some signs of wear where the hub is moving inside the rubber. I would think you could spray some soapy water on them to see if it has an effect. If you still have the noise, its probably not the bushing.

Also assuming that you put in stock bushings and not some aftermarket urethane ones.

Interesting.
If they dont squeeke when they are new and tight, then maybe swelling the rubber to make them tight again should be the goal.
And not lubricate them, which will hold dirt and grind even more rubber away.

But obviously i dont know, just sharing my thought.
